Haworthias are dainty succulent houseplants and are frequently compared and confused with Aloes, and Gasteria plants, this is hardly surprising since they're all members of the Asphodeloideae family. However, unlike Aloes, Haworthias are almost always small and very (very) slow growing plants.They don't need much fuss or care and can even go many weeks without water if required. They also tend to look brilliant in unusual containers or interesting soil mixes.
LIGHT- Plant in an area of your garden that gets 4-6 hours of sunlight in the morning. If given more sunlight it will turn a deep red color showing it is stressed. Too much sun will cause it to turn white and dry up. If grown indoors, place in a window that gets plenty of sun.
WATER- Water every 7 to 10 days, making sure the soil is dry before each application. When the temperature drops in the fall, Haworthia requires less water. In the spring, water every 2 to 3 weeks, as long as the soil is dry before each watering. Haworthia requires much less water during the winter.
Problem - The plant is basically rotting. ... Wrinkling leaves on a Haworthia are normally caused by either no water for a prolonged period or too frequent watering. If you look back on how the plant has been watered over the last few months you should be able to judge which is the cause and adjust.
